MPI_Op_free(3)

NAME
     MPI_Op_free - Frees a user-defined combination function handle

SYNOPSIS
     C:

          #include <mpi.h>
          int MPI_Op_free( op )
          MPI_Op  *op;


     C++:

          #include <mpi.h>

          void Op::Free()


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER op, ierror

          CALL MPI_OP_FREE(op, ierror)


STANDARDS
     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Op_free routine frees a user-defined combination function handle.
     This routine accepts the following parameter:

     op   Specifies the operation. On exit, op is set to MPI_OP_NULL.
          (handle)

     ierror
          Specifies the return code value for successful completion, which is
          in MPI_SUCCESS.  MPI_SUCCESS is defined in the mpif.h file.
